Paging Bandwidth Segmentation for Limited-Capacity Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices may fail to receive paging messages due to the paging bandwidth exceeding their capacity, leading to reception issues.
Innovation Solution
Configure paging bandwidths within a system bandwidth that do not exceed the minimum bandwidth capacity of the terminal device, allowing each paging bandwidth to be tailored to the device's capabilities, and utilize frequency domain positions and beams for efficient message transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the paging bandwidth is configured to cover the entire system bandwidth, then the paging message can be transmitted with high capacity, but terminal devices with limited bandwidth capacity cannot receive the paging message
Solution Approach 1:
The system bandwidth is divided into multiple bandwidth parts (BWPs), and paging bandwidths are segmented within these BWPs. Each terminal device can be assigned a specific paging bandwidth that matches its capacity, while the overall system maintains high paging capacity through multiple segmented bandwidths. This resolves the contradiction by breaking down the large system bandwidth into smaller, manageable segments that individual terminals can handle.
Solution Approach 2:
Different bandwidth configurations are assigned to different terminal devices based on their specific capabilities. Each terminal receives a customized paging bandwidth configuration that matches its local bandwidth capacity, rather than using a uniform system-wide bandwidth. This ensures that each terminal can reliably receive paging messages while the system overall maintains high capacity.
2Adaptability or versatility
If multiple paging bandwidths are configured for different terminal devices, then all devices can receive paging messages, but the system complexity increases
Solution Approach 1:
The paging bandwidth configuration is made dynamic and adjustable based on terminal device capabilities. The network can flexibly assign different bandwidth sizes and positions to different terminals, and these configurations can be updated as needed. This dynamic approach enables adaptability to various terminal capacities while managing complexity through flexible, on-demand configuration rather than fixed complex structures.
Solution Approach 2:
The bandwidth part (BWP) mechanism serves multiple functions: it provides bandwidth adaptation for different terminals, enables efficient resource allocation, and supports flexible paging bandwidth configuration. By using this multi-functional mechanism, the system achieves high adaptability without proportionally increasing complexity, as the same BWP framework handles multiple aspects of resource management.
3Reliability
If the paging bandwidth is reduced to match terminal device capacity, then all devices can receive paging messages, but the overall paging message transmission capacity decreases
Solution Approach 1:
The system bandwidth is segmented into multiple bandwidth parts, and each terminal device is assigned a specific paging bandwidth segment that matches its capacity. While individual terminals use smaller bandwidths for reliable reception, the overall system maintains high transmission capacity by utilizing multiple segments simultaneously for different terminals. This segmentation allows the system to achieve both reliability for individual devices and high overall productivity.
Solution Approach 2:
Multiple paging bandwidths assigned to different terminals are combined to achieve overall high system capacity. While each individual terminal uses a limited bandwidth matching its capacity, the aggregation of multiple such bandwidths across the system provides sufficient total capacity for high-volume paging operations. This merging approach ensures that reliability at the terminal level does not compromise overall system productivity.
